Embodiment 1
[0021] Such as figure 1 As shown, this embodiment provides a light-emitting device, including a light-emitting diode 10, the light-emitting device also includes a thermoluminescent layer 15 arranged on one side of the light-emitting diode 10, and the thermoluminescent layer 15 is used to absorb the light-emitting diode 10 during the light-emitting process. The heat generated in the device emits light to enhance the light-emitting brightness of the light-emitting device.
[0022] The light emitting diode 10 may be an organic light emitting diode including a stacked cathode, an organic composite light emitting layer and an anode. The organic light emitting diode can also optionally include an electron transport layer, a hole transport layer, etc. to improve luminous efficiency. Of course, the light emitting diodes 10 in the above light emitting devices may also be horizontal inorganic micro light emitting diodes or vertical inorganic micro light emitting diodes.

Embodiment 2
[0030] refer to figure 2 and image 3 , this embodiment provides a display substrate, including a plurality of sub-pixels, each sub-pixel includes a light-emitting device, at least one sub-pixel is a high-brightness sub-pixel, and the light-emitting device in the high-brightness sub-pixel is the above-mentioned embodiment 1 Light emitting devices.
[0031] That is to say, the light-emitting device provided in Embodiment 1 is applied to a display substrate, so as to reduce the temperature of the display substrate and increase the brightness displayed by sub-pixels. Each sub-pixel usually also includes a driving circuit for driving the light-emitting device, and the thermoluminescent layer 15 can also absorb the heat released by these driving circuits, thereby reducing the temperature of the driving circuit, which is beneficial to the stability of the system.
[0032] figure 2 Three light-emitting devices are shown in . The light emitting diode 10 in the light emitting dev...
Embodiment 3
[0050] This embodiment provides a display device, including the above-mentioned display substrate.
[0051] Specifically, the display device can be an inorganic micro-light-emitting diode (Micro-LED) display panel, an organic light-emitting diode (OLED) display panel, a mobile phone, a tablet computer, a TV set, a monitor, a notebook computer, a digital photo frame, a navigator, etc. A product or part showing a function.
